E. L. SEAL DOOR STOP Dec. 12, 1967 Filed June 13, 1966 W. 2 W5 5 L M M m 7 6 0 5% B 5 1 L United States. Patent 3,357,732 DOOR STOP Edgar L. Seal, 10246 Rosewood Ave, South Gate, Calif. 90280 Filed June 13, 1966, Ser. No. 556,992 6 Claims. (Cl. 292-60) This invention relates to a door stop or retainer and has for an object to provide a device of this nature that has retention engagement with the free end of a door to hold the same in a resilient and non-marring manner, and to accommodate to doors of different thickness and under conditions, such as wind and other forces, that tend to cause the door to rattle.

Another object of the invention is to provide a door stop, as above characterized, that, by compound movability of its door-retaining means, enables automatic adjustment to door thicknesses and operator-controlled adjustment between door-engaging and disengaged positions.

The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.

The above objects are realized in a door stop that is provided with a mounting portion that has a pad to engage one side of an open door and a bearing located beyond said pad with respect to the door edge, a swivel portion having engagement with said bearing on the mounting portion, and also has a pad, opposed to the mentioned pad, to engage the opposite side of the door, and spring means that has the dual function of imposing a resilient bias on the swivel portion to draw the pad thereof in a direction toward the pad of the mounting portion to provide a resilient door holder, and of creating a frictional force on the said swivel portion that holds the same in either of its operative positions-holding the door or released therefrom.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description and which is based on the accompanying drawing. However, said drawing merely shows, and the following description merely describes, one embodiment of the present invention, which is given by way of illustration or example only.

In the drawing, like reference characters designate similar parts in the several views.

FIG. 1 is a plan view, partly in section, of a door stop according to the present invention and shown holding a door open.

FIG. 2 is a front elevational view of said door stop in released position.

FIG. 3 is an enlarged and fragmentary sectional view as taken on the line 33- 3 of FIG. 1.

The drawing shows a baseboard 5 which is representative of a wall for mounting the present door stop, and a door 6, of which only the free edge is shown, and which is held open by the stop. The baseboard 5 represents not only a wall, but any other place or area, near or spaced from the floor, adapted to have the door stop affixed thereto in a position suitably related to the door edge to engage the same anywhere along its height.

The present door stop comprises, generally, a mounting portion 10, a swivel portion 11 carried by the mounting portion, spring means 12 to bias the latter portion in a direction to resiliently clamp the door against the mounting portion and to create friction on the swivel portion to retain the same in set positions, rotatively, and means 13 to limit said set positions.

The mounting portion is shown as provided with a 3,357,732. Patented Dec. '12, 1 967 "ice mounting base 15 that, by means such as screws 16, may be aflixed to the baseboard 5 and to project into the space adapted to be occupied by the edge of door 6, a buffer pad 17 on the face of said base 15 adapted to be engaged by a face of door 6, and a tubular extension 13 offset from the pad 17 and extending forwardly. Said extension is provided with a bearing 19 intermediate its ends, a cavity 20 being defined in the rear end directed toward the baseboard, and a cavity '21 that is outwardly directed.

The swivel portion 11 is provided with an arm 22 that has a buffer pad 23 and, at the end offset from said pad, is provided with a hub 24 that is in sliding and rotational engagement in cavity 21 of the tubular extension. The arm 22 is so proportioned that the same and the base 15 and the respective pads 23 and 17 thereof are in opposed relation.

The spring means 12 is shown as a coil spring 25 in the cavity 20, and a stud 26 with a shank in bearing engagement in the bearing 19, a head 27 on one end of said stud with the spring 24 confined between said head and the bearing 19, and a threaded opposite end 28 on said stud connected to said hub 24 of the arm 22. It will be clear that said spring 25 normally expands to cause the hub 24 to be retracted into the cavity 21, in which case the space between the pads 17 and 23 is minimum. The arm 22 will adjust itself to the thickness of the door 6, the spring 25 being under bias accordingly.

The means 13 is shown as a radial pin or stud 29 on the hub 24, and abutment edges 30 and 31 for said pin, preferably apart, on the tubular extension 18 which, as can be seen in FIG. 3, limit the rotative movement of the arm 22 between the door-holding position of FIG. 1 and the release position of FIG. 2.

In practice, with the door held as in FIG. 1, in open position, the bias of spring 25 constitutes a clamping force on the door that obviates rattle. When release of the door is desired, the arm 22 is raised to the position of FIG. 2, releasing the door to close by itself or to be closed. The friction of the ends of the spring on the stud head 25 and the bearing 19 retains said arm in such released position. Hence, when the door is again opened to be so held, the door edge is free to be brought into contact with the pad 17. Then, the arm is pulled forwardly against the bias of spring 25, turned 90, as limited by the engagement of the pin 29 with the abutment edge 31, and released so that the spring 25 may draw the arm 22 into door-clamping engagement with the pad 17.

It will be clear that the arm 22 retains its set position greatly facilitating a door-holding and a door-releasing operation.

While the foregoing has illustrated and described what is now contemplated to be the best mode of carrying out the invention, the construction is, of course, subject to modification without departing from the spirit and scope of the invention. Therefore, it is not desired to restrict the invention to the particular form of construction illustrated and described, but to cover all modifications that may fall within the scope of the appended claims.

Having thus described the invention, What is claimed and desired to be secured by Letters Patent is:

1. A door stop comprising:

(a) a base part provided with a door-side-engaging buffer pad and a forwardly directed tubular extension, provided with a bearing laterally offset from said pad,

(d) means to limit rotational movement of said arm between door-engaged and door-released postions.

2. A door stop according to claim 1 in which the rotational-limiting means comprises relatively slidable portions of the tubular extension and the hub extending thereinto.
